"This invention relate-s qto -new:-an'd useful im The invention has forobject the construc- =tin of'a b ook mark -which is characterized by aninverted U 'sh'aped' resilient stri-p adapted to -be engaged on the topportion of the back of the binding'of a book and at its top end having aforwardly projectingsection, atop strip associated with said U-shapedstrip "and section in a certain mannenand amark properassociated' withthe top strip.

More specifically, it is contemplated to hingedly mount the top strip onthe rear of the U-shaped striplanii to provide it with a iiawportionengage Still further it is contemplated to provide the top stripwith a horizontal forwardly extending end portion, and to provideau-shaped strip pivctally mounted at its ends upon"said forwardlyextending portion and to pivotally depend the mark proper from the outerend of the U-shaped strip.

Still further the invention contemplates the provision of an auxiliarystrip on the top strip engageable with one arm of the U-shaped strip forfrictionally holding the latter in various positions.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a fragmentary perspective view of a book with a book markmounted thereon and constructed in accordance with this invention.

Fig. 2 is a fragmentary vertical sectional view of Fig. 1 showing the'book mark in elevation.

Fig. 3 is a perspective view of the book shown in Fig. 1 opened up andwith the book mark proper pulled out and swung backwards.

Fig. 4 is a fragmentary enlarged elevational view of a portion of thebook mark looking in the direction of the line 4-4 of Fig. 2.

Fig. 5 is an elevational view of a book mark constructed in accordancewith a modification of this invention.

The book mark in accordance with this invention, includes an invertedU-shaped strip IU of resilient material having a front arm and a reararm III. This U-shaped strip is adapted Application December 11,1e45,S'erialfN6IG34L'I7'Z 2Olaims; curiae-r199 i ftOpngage'upOntHe topportion of the b'ack' of the "Binding "I?! ofeflb 'fifillfi l L-'FheTI-Ofit' ar'ih F e 1s shorter than the-*rear arm fiil Th'ese armshavetheir-bottom ends formediwit esued c pbrt'ions I25" respectively}d-irected inwards and "calculated to more fiimly 5/ grip andf'enlga'jgethe binding of the book: "The-ffont 'ariii lll is provide'd Witha-forward1y-prbjecnng section a at "its top which is J adapted whenpressed rear- 10 "wardstoioenthearms =1 8W 6 togethenupo'n Theselugsl'd-areidrmed itite terial .of the U-shaped strip.

The top strip I4 is also provided with a forwardly extending endportion l lc extending forwards from the jaw portion 14 A substantiallyU-shaped strip 18 is pivotally mounted at the ends of its arm-s upon theforwardly extending end portion |4 by a. pintle I9. The arms of theU-shaped strip l8 engage respectively above and below the end portion ofthe forwardly extending end portion M The pintle I9 engages throughthese three parts.

A marker proper 2B pivotally depends from the outer end of the U-shapedportion of the U- shaped strip l8. This mark proper comprises a fiatpiece of material 211 mounted upon the bottom end of a relatively thinstem 20 This stem extends into a slot 2| formed in the bend of theU-shaped strip It. The inner end of the stem 20 is provided with aspherical head 20 which forms a bearing by which the mark proper 29 maybe pivoted upwards and downwards. The mark proper 20 may move from thevertical position illustrated in Fig. 2 upwards substantially to ahorizontal position above the pages Ill of the book H.

The operation of the device is as follows:

In Figs. 1 and 2 the book mark is shown in actual use. The mark proper20 may be engaged between difierent pages merely by pivoting it upwardsabove the top edges of the pages II and then swivelling the U-shapedstrip Hi to the right or left, as desired, and allowing the mark proper20 to then move downwards into its new position. The book mark may beremoved from the book by 55 first pivoting the top strip l4 upwards sothat its jaw portion I4 disengages from th forwardly projecting sectionIll of the U-shaped strip 10,

Fig. 3 illustrates the parts in this position. Now the U-shaped strip l0may be pulled off the binding I l f the book. Y

In Fig. 5 a modified form of the invention has been disclosed whichdistinguishes from the prior form in the fact that the top strip [4 hasa bottom continuation M continuing from the pivot l5 frontwise andextending over the top of the U-shaped strip l0 and continuing into ajaw portion H disposed directly beneath and engaged by the jaw portion MThe jaw portion M engages over and holds the forwardly projectingportion Ill". The jaw portion M supplements the holding action of thejaw portion M A forwardly extending end portion M continues from the jawportion l 4 and extends to a position directly beneath the bottom arm ofthe U-shaped strip l8. Afpiece of friction material 22 is cemented uponthe top face of the end portion l4 and frictionally engages the bottomface of the bottom arm of the U-shaped strip l8 for frictionally holdingthe U-shaped strip I8 in various pivoted positions upon the pintle rivetHi. In other respects this form of the invention is similar to theprevious form.

A feature of this form of the invention resides in the fact that theU-shaped strip 18 is not loose,

in that it is frictionally held by the forwardly exis reserved to allchanges and modifications coming' within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patents is:

1. A book mark comprising a U-shaped member providing opposing materialgripping jaws having terminals spaced longitudinally from each other andprovided with curled ends adapted to engage a book part, said U-shapedmember having a loop on the bend part thereof, hinge lugs secured tosaid member inwardly of said loop, a lever pivoted to said lugs andprovided with a loop engaging the loop of the member to close said jawsagainst a EMIL POLAK.
